From 02c568bdea3eccf65a539335d13a3c95e0144929 Mon Sep 17 00:00:00 2001 From: northersubair <294447266+northersubair@users.noreply.github.com> Date: Sat, 17 Oct 2026 15:01:41 +0100 Subject: [PATCH] northersubair: event tests for edit/delete/moderate (#1427, #1428) Implements the two contract test issues selected for this branch. Both add coverage only: no production contract code is touched. #1427 - event tests for gist_edited and gist_deleted: - editing_a_gist_emits_gist_edited: asserts the topic is "gist_edited" and that the payload decodes to the updated Gist (so an indexer can read the new content pointer without another call) - deleting_a_gist_emits_gist_deleted: asserts the topic is "gist_deleted" and the payload is the deleted gist id, and that the gist is gone afterwards #1428 - event tests for hide, unhide, remove and report: - hiding_a_gist_emits_gist_hidden - unhiding_a_gist_emits_gist_unhidden (asserted on the last of the two moderation events) - removing_a_gist_emits_gist_removed (plus the gist is gone) - reporting_a_gist_emits_gist_reported_with_a_running_count: asserts the topic and that the published (gist_id, count) pair moves 1 -> 2 across reports, matching the return value and report_count() A small `last_event` helper decodes the most recent event, so the assertions work whether `env.events().all()` is cumulative or per-invocation. A silent rename of a topic symbol breaks every downstream indexer, so all assertions are deliberately literal. cargo test: 32 passed (26 before, 6 added).
